PROBLEM TO BE SOLVED: To provide: an apparatus for evaporating waste water to reduce acid gas emissions; and a method of realizing an apparatus that reduces emissions such as air pollution and also reduces waste water discharge.SOLUTION: An apparatus for evaporating waste water and reducing acid gas emissions includes evaporator devices 7, 31 configured to receive a portion of flue gas emitted from a boiler unit 1 and waste water to directly contact the flue gas with the waste water to cool and humidify the flue gas and to dry solid particulates within the waste water. In some embodiments, the waste water may be a component of a mixture formed by a mixer device 25 prior to being contacted with the flue gas to humidify and cool the flue gas and dry solids within the waste water. An alkaline reagent and activated carbon are mixed with the waste water prior to the waste water contacting the flue gas. Solid particulates that are dried within the cooled and humidified flue gas are separated from the flue gas via a particulate collector 9. |
